Hybrid Speciation

A major challenge, and one that I believe we are having with the Lake
Victoria haplochromines, is that of adequately dealing with early stages
of lineage splitting.  In the real world, this does not happen exactly the
way that Croizat or Hennig seemed to have in mind.  Some landscapes
shatter, rather than divide evenly, producing scores of vicariants that
may alternately achieve the level of semispecies, then anastomose, back
and forth, until some decisive event puts an end to the confusion.   I've been calling this "the webbing at the node."  Has anybody
else out there been thinking about this?
